About it

copy-glob is a small utility to copy files to an output directory using glob syntax. Inspired by copy_to_output.

How to use

Add a crate to the build dependencies in Cargo.toml.

[build-dependencies]
copy-glob = "0.1"

Create build.rs and add the following to it:

use copy_glob::{get_target_folder, copy_glob};

fn main() {
    let output = get_target_folder().join("copies"); // target/{debug,release}/copies
    copy_glob("**/for_copy/*", output);
}

This will copy all the files in the directory, preserving the structure, since the copying starts from the root of the project (where the Cargo.toml file is located).

To localize the file search somehow, you can use the following code:

use copy_glob::{get_target_folder, get_root_path, CopyGlobOptionsBuilder, copy_glob_with};

fn main() {
    let output = get_target_folder().join("copies");
    let root = get_root_path().join("for_copy"); // same level as Cargo.toml
    let options = CopyGlobOptionsBuilder::new().set_root_path(root).build();
    copy_glob_with("*.toml", output, &options);
}

This will copy all files with the .toml extension in the for_copy folder without preserving the structure.

In addition, you can add exceptions from where files will be copied. By default, the target directory hangs in the excludes.

let options = CopyGlobOptionsBuilder::new().add_exclude("**/some_pattern/*").build();
